Implant Detection and Initialization
At the completion of the 30-minute Implant Detection period,
Remote Rate Profile Optimization is enabled; the appropriate pacing
and sensing polarities are automatically selected by the device;
Ventricular Output Management is enabled and Amplitude and Pulse
Width become adaptive. Reduced VP™+ is enabled 60 minutes
after Implant Detection is complete.

aThe atrial and ventricular rate limit is 200 min-1 (± 20 min-1).
bTolerance for amplitudes from 0.5 V through 6.0 V is ± 10% and for
7.5 V is -20/+0%. Tolerances are based on 37°C and a 500Ω load.
Amplitude is determined 200 μs after the leading edge of the pace.
